CENTRIFUGAL FORCE-PUMP.

SPECIFICATION forming part of Letters Patent No. 450,491, dated April14, 1891.

Application filed May 13, 1890. Serial No, 351,683. (No model.)

To all whom it may concern.-

Be it known that we, EDWARD S. NICHOLAS and JOSEPH R. TURNER, ofGreenville,in the county of Darke and State of Ohio, have invented a newand Improved Centrifugal Force-Pump, of which the following is a full,clear, and exact description.

The object of the invention is to provide a new and improved centrifugalforce-pump, which is simple and durable in construction, very effectivein operation, designed to raise light or heavy liquids, and adapted tobe used for filling tanks, irrigating land, as a domestic pump, foroil-pipe lines, water-works, due.

The invention consists in certain parts and details and combinations ofthe same, as will be described hereinafter, and then pointed out in theclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improvement. Fig. 2 is asectional plan view of the cone. Fig. 3 is a sectional side elevation ofpartof the same on the line mm of Fig.2. Fig. 4 is a sectional plan viewof a modified form of the cone, and Fig. 5 is a sectional side elevationof amodified form of the improvement.

The improved centrifugal force-pump A is provided with a casin g B,havinga center wall formed in the shape of an inverted cone 0, from theapex of which extends downward the suction-pipe D, provided with acheckvalve E. The central cone 0, at its base B, terminates in anannular curved flange Q, from which extends downward the annular innerwall 0 provided with an outwardlyextending flange or base 0 The casing Bis provided with a cover F, having the inverted cone G in its center,from which extends, at the circumference, the downwardly-curved annularflange G, terminating in an outer wall G reaching to the base 0 andsecured to the latter by suitable means. The casing B thus formed has aninverted-cone-shaped space H, from which extends a downwardlycurvedannular space 11, leading to the water-receptacle H formed between theinner and outer walls and the base, as is plainly shown in Fig. 1. Fromthis water-receptacle H leads a discharge-pipe I.

In the inverted-eone-shaped space H is I mounted to turn an invertedduplex or hollow cone K, formed of two spaced concaved disks, andprovided in its apex with a downwardlyextending short neck K, openinginto the suction-pipe D, so that the water passing to the lattercan passdirectly into the interior of the duplex or hollow cone K. The hollow orduplex cone is provided at its base with the curved annular ring Kextending into the similarly-shaped part H of the casing B, and the saidcurved ring K is provided with a continuous annular outlet K discharginginto the waterreceptacle H The upper conical disk or cover K of theinverted hollow cone K is secured by suitable bolts or screws to thelower conical disk or main body, as is plainly illustrated in Figs. 2and The opening in the hollow cone K decreases from the center to thecontinuous opening K by reason of the difference in the angles of thetwo disks, said angles being on lines which intersect at the base of theduplex cone, and the area of the latter is somewhat less than thecross-section of the suction-pipe D.

The fastening-screws pass through the cover K into bosses K preferablyarranged at or near the curved part or base of the cone. Between thebosses K is left sufficient space which forms port-holes or orifices, soas to leave a continuous passage in the cone from the apex to thecircumference of the rim. Extra enlarged ports may be formed in theopening K to permit impuritiessuch as sand and pebbles-to pass to theoutside. In

case they are used the entire discharge-opening should be slightlylarger in area than the cross-section of the suction-pipe.

From the center of the cover K extends upward a hub K mounted to turn insuitable bearings G formed in the cover Got the easing B. In the hub Kis secured a hollow shaft L, provided with a fixed bevel gear-wheel L,meshing into a gear-wheel N, secured on the horizontally-extending shaftN, mounted to turn in suitable bearings formed on the cover Gof thecasing B. The shaft N is provided with a pulley N connected withsuitable machinery, so as to impart a rotary motion to the said shaft N,which rotarymotion is transmitted by the gear-wheels N'and L to theshaft L, whereby the hollow cone is rotated within the casing B. Theupper end of the shaft L is adapted to be closed by a cap L which can beremoved to permit of filling or priming the cone, as hereinafter morefully described.

From the base C of the casing B leads a pipe 0, provided with a valve 0,and connected with an air-chamber P, provided near its top and bottomwith valves P and P From the top of the air-chamber P leads a pipe Q,opening into the space H of the eas ing B, the said pipe being providedwith a valve Q and an air-cock Q located above the highest point of thecasing B.

As illustrated in Fig. t, the cone K may be provided with an interiorspiral R, which commences at the neck K and terminates near the base, sothat the water passing through the cone travels along the spiral beforeit is discharged at the opening K as illustrated in Fig. 5. The cone Kis solid and is provided on its under side with a spiral It, filling thespace between the hollow cone K and the cone C.

The operation is as follows: \Vhen the pump has been set up and thesuction-pipe D extends into the liquid to be pumped, then the operator,in order to start the pump, first removes the cap L and then fills thesuctionpipe D and the cone K with liquid. A rotary motion is nowimparted to the shaft N, as previously described, so as to revolve thecone K within the casing B, whereby the centrifugalforce causes thewater in the cone K to discharge through the opening K so that thevacuum produced in the cone K causes the water to rise from thewateusupply into which the suction-pipe D extends. The water 3 lifts oropens the check valve E, passes through the suction-pipe into the coneK, and is continuously discharged through the opening K of the latter aslong as the cone revolves. The water is forced from the casing B throughthe outlet-pipe l to any desired place.

It is understood that the quantity of water sucked up and discharged bythe cone K depends upon thesize of thelatterand the speed at which itrevolves. When the spiral R is used, as previously mentioned, then thepower of the revolving spiral is added to the centrifugal force of thecone K. When the rotary motion of the cone K ceases, the water held inthe cone at the time comes to a state of rest in the cone and the latterremains filled, so

that the pump is ready to be started again at any time without a newpriming or filling, as

previously mentioned. It is understood that the cone K is fitted asclose as possible into the casing B, so that the cone revolves in avacuum, whereby the friction is diminished to a minimum. It will furtherbe seen that when the water has passed to the base of the cone K itflows downward by gravity through the curved annular part K to bedischarged at the opening K into the Water-chamber H Any air which maybe between the cone K and the cone C is forced outward into thewater-receptacle H whenever the cone K is set in motion, as thecentrifugal force moves the air in that direction.

The air-pump P is used when high pressure is desired in the casing B, soas to force the water from the latter through the pipe to a longdistance or a great height. In order to do this the valves 0 and Q areopened when the pump is running, so that water from the casing B canpass through the pipe 0 into the chamber P, so as to force the air outof the latter through the pipe Q. into the top of the casing B, wherebypressure is exerted on the water contained in the casing. Now by closingthe valves 0 and Q and opening the valves P and P the water in thechamber P will be drained out and the chamber again filled with air. Theval-ves orfaucets P and P are then again closed and the valves 0 and Qare again opened, so that water passing through the pipe 0 again intothe chamber P forces another quantity of air into the casin B, so thatadditional air-pressure is exerted on the body of water in the saidcasing. This operation can be repeated until the desired air-pressure isobtained in the casing.

By having the apex of the cone K downward, as previously described, thepump will always be filled with water ready to be started wheneverdesired. By providing the cone K with the annulardownwardly-extendingpart K the water has a free discharge from the said cone, as it flowsdownward by its gravity after leaving the base of the cone proper.

Having thus fully described our invention, we claim as new and desire tosecure by Letters Patent- 1.
